Debunking The 10 Biggest Myths About Metal Roofs
1. Does A Metal Roof Attract Lightning? Metal is known for being a good conductor of electricity, so we have to assume that is why this common misconception exists.
Lightning seeks a path to the ground and almost always will strike any object that is highest in the area, but that also has a direct path to the ground. Since a metal roof is not grounded, lightning has no reason to strike it.
Long story short about metal roofs and lightning: if lightning strikes your house, it will not be because of your roof. The odds of a lightning strike hitting a metal roof are the same as any other type of roofing material.
What happens when lightning strikes a metal roof? In the unlikely event that your house was struck by lightning, you would actually be safer with metal roofing since it’s not combustible and will not ignite and catch fire.
2. Are Metal Roofs Loud?
I get asked the question, Are metal roofs noisy on a regular basis and it's simply not true. While a metal roof can be noisy when it rains, it doesn’t have to be. In fact, a metal roof can block out just as much noise as most other types of material. It all depends on the installation of the metal roof.
Residential metal roofs are generally installed over solid wood decking with a protective underlayment. Any attic space is also insulated. These additional layers absorb and muffle the sound of rain hitting the roof. The protective barrier makes it much quieter than if the roof was installed directly on an open frame.
3. Does Metal Roofing Rust?
Metal roofing is a durable material that has a lot of protection against rust. Most metal roofs will have a galvalume® coating applied to the steel as a rust inhibitor. In addition, the material is painted to further reduce the likelihood of rust. So yes, eventually a metal roof will rust, but it should take a long time before that happens.
4. Do Metal Roofs Dent?
Metal has great durability and a class 4 impact rating which helps reduce the likelihood of the metal denting or becoming punctured.
5. Are metal roofs hotter than shingles? While it’s true that metal exposed directly to the sun will heat up, the same is true of any roofing material. High-quality metal products are now made to combat solar heat that is known as “cool roofing”.
A cool roof is a roofing system that delivers higher solar reflectance and high thermal emittance (the ability to radiate absorbed, or non-reflected solar energy) than standard designed roofing products. These products have heat-reflecting coatings that can fully reflect even 50% of infrared wavelengths. Cool metal roofs aren't as hot as shingle roofs.
6. Do Metal Roofs Affect Cell Phone Reception?
The roof can create a shield that blocks the radio frequency (RF) signals used by cell phones. This can be an issue with any type of thick roofing material, including wood and asphalt.
7. Are Metal Roofs Expensive Yes, in the short term a metal roof cost about twice as much as a shingle roof. In the long term though it will actually save you money.
8. Can You Put Solar Panels On A Metal Roof? Yes, there are brackets that serve as solar panel mounts for the metal roof.
9. Are Metal Roofs Reflective? It depends on the paint finish and the paint color.
